Temporary Radiator Removal

We are remodeling our bathroom and need to shut off the radiator in our bathroom in order to remove it and drywall the wall behind it. My question is, knowing how to shut just this radiator off but shutting down the valve, will we have heat going to the other radiators so that we are not without heat while the remodel takes place? Being as it is November in Maine, taking the heating system down is not an option for more than a day and this project is going to be at least three. Want to make sure we can get it done without freezing or having to wait until spring.

Without knowing how the system is piped, it's hard to say. Unless it is a series system, you should be able to just cap the pipes. Note that the tile and prep to the subflooring will probably change the height of the floor, and the pipes may no longer line up.
